    • A method for fabricating buried bit lines comprises steps of: defining a plurality of parallel masked regions and a plurality of first etched regions each forming between any two neighboring masked regions on a surface of a substrate, and wherein the masked region is wider than the first etched region; etching the first etched regions to form a plurality of first trenches and a plurality of first pillars; forming two bit lines respectively on two sidewalls of each first trench; etching the first pillars to form a plurality of second pillars corresponding to the bit lines. The present invention uses a two-stage etching process to prevent pillars from bending or collapsing due to high aspect ratio. Moreover, the present invention has a simple process and is able to reduce cost and decrease cell size.
    • 一种用于制造掩埋位线的方法包括以下步骤:限定多个平行掩蔽区域和多个第一蚀刻区域,每个第一蚀刻区域形成在衬底的表面上的任何两个相邻的掩蔽区域之间,并且其中所述掩蔽区域比所述第一蚀刻区域宽 蚀刻区域 蚀刻第一蚀刻区域以形成多个第一沟槽和多个第一柱; 分别在每个第一沟槽的两个侧壁上形成两个位线; 蚀刻第一柱以形成对应于位线的多个第二柱。 本发明使用两级蚀刻工艺来防止柱由于高纵横比而弯曲或折叠。 此外,本发明具有简单的过程,并且能够降低成本并减小单元尺寸。

    • A lens apparatus can be easily set even in cases where the lens body and demands are distant from each other upon shooting without a decrease in reliability. A lens body mounted on a camera body is provided with a command signal converting unit, a time-series position signal converting unit, a wireless communication unit, a communication condition monitoring unit and a communication process switch unit. A signal converting unit, to which a zoom demand and a focus demand are connected, is provided with a time-series command signal converting unit, a position signal converting unit and a wireless communication unit. The lens body and the signal converting unit are configured to wirelessly communicate with each other to eliminate the use of connection cables, thereby improving operationality while enabling highly reliable wireless communication.
    • 即使在不降低可靠性的情况下,透镜体和拍摄体在拍摄时彼此远离的情况下也可以容易地设定透镜装置。 安装在照相机主体上的镜体设置有命令信号转换单元,时间序列位置信号转换单元,无线通信单元,通信条件监视单元和通信处理开关单元。 具有连续变焦需求和焦点需求的信号转换单元设置有时间序列指令信号转换单元,位置信号转换单元和无线通信单元。 透镜体和信号转换单元被配置为无线地彼此通信以消除连接电缆的使用,从而在实现高度可靠的无线通信的同时提高操作性。
